Leveraging the Internet of Things and Analytics for Smart Energy Management

Optimizing lighting
The EMS monitors the Air Handling Unit parameters to maintain optimal air circulation for dynamic
occupancy. This helps ensure that occupants can comfortably breathe and work in their respective rooms.
With such a system in place, lighting can also be automatically turned on when the first person enters the
room and automatically turned off in case the last person to exit the room forgets to do so.
When granular occupancy information is available, the EMS effectively governs the required lighting for
individuals who are entering or exiting. Similarly, the EMS can interact with workstations to determine if
they can be turned off or not. The workstations send information to EMS over the LAN that no active
thread is running and the EMS then validates that the user has, in fact, exited the building. It then sends
instructions to the workstation to turn itself off.
